US 8,210,113 B1 · Web cutting and sewing apparatus

Abstract

A sewing system is disclosed for facilitating the sewing together with a sewing machine ends of at least two webs that are held by a spooling machine. A substantially horizontal carriage rail is supported by a support mounting means in fixed relationship with the spooling machine and itself slidably supports a sewing carriage adapted to hold the sewing machine. A trimming carriage is also slidably supported on the carriage rail and supports a conventional trimming machine that trims the ends of each web ahead of the sewing machine. The trimming carriage is selectively and mechanically fixed with the sewing carriage with a mechanical fastener, so that as the sewing carriage is moved along the carriage rail, the trimming carriage is also moved along thereby. A substantially horizontal support platform is fixed with the carriage rail and adapted to hold each web fixed with respect thereto with a plurality of vertically-movable pins that traverse each web in a raised position.

Dependent claims

A sewing system for facilitating the sewing together with a sewing machine ends of at least two webs held by a spooling machine, the system comprising:

a substantially horizontal carriage rail having a proximal end, a distal end, a forward side, a rearward side, a top side, and a bottom side, the carriage rail further including a support mounting means adapted to support the carriage rail in a substantially fixed relationship with the spooling machine;
a sewing carriage slidably supported on the carriage rail and adapted to hold the sewing machine thereon;
and
a substantially horizontal support platform fixed with the carriage rail and adapted to hold each web fixed with respect thereto such that the sewing machine can sew the webs together as the sewing carriage is moved from the proximal end of the carriage rail to the distal end thereof;
the carriage rail further including a linear rack gear fixed thereto and spanning substantially the length of the carriage rail from the distal end to the proximal end, the sewing carriage further including a pinion gear engaging the rack gear when the sewing carriage is supported on the carriage rail, such that rotating the pinion gear moves the sewing carriage on the carriage rail, the system further including a drive means for selectively rotating the pinion gear in either direction.
